I have some issues with my lightning Page. There are some lightning components who are filled with some data that came from more than one service.

There is a component Asset Contact, the data from this component are not saved in Salesforce, we just consume the service. There are 2 methods on this component one gets the contact info and the other update this contact, when we click we open a modal that give us permission to edit this contact. After that for some reason it get the error of uncomitted saying that need to wait DML transaction, but there isn't any DML during this process.

Hi Fábio, welcome to SFSE. Please take a moment to scroll through the tour and read How to Ask. Your question is more likely to receive a positive answer if you edit its content to include a specific question such as "How do I X?" or *Why do I observe Y?".
